Defending the European Energy Infrastructures is a research project funded by is a research project funded by the European Comission under the Horizon2020 programme (Call: CIP-2016-2017-1. Topic: CIP-01-2016-2017). Critical Energy infrastructures (CEI) protection and security are becoming of utmost importance in our everyday life. However, cyber and system-theoretic approaches fail to provide appropriate security levels to CEIs, since they are often used in isolation and build on incomplete attack models, resulting in silos-like security management fragmented operational policies. To face these challenges, DEFENDER will (i) model CEIs as distributed Cyber-Physical Systems for managing the potential reciprocal effects of cyber and physical threats (ii) deploy a novel security governance model, which leverages on lifecycle assessment for cost-effective security management over the time (iii) bring people at centre stage by empowering them as virtual sensors for threat detection, as first level emergency responders to attacks, or by considering workforce as potential threats. DEFENDER will adapt, integrate, upscale and validate a number of TRL 4-5 technologies and deploy them within a TRL7 integrated yet adaptable framework for CEI security, resilience and self-healing “by design”, with a view to address, detect, and mitigate cyber-physical threats.
Our role: Participate in defining a dynamic security service level agreement (DS-SLA) concept to mitigate threats and to optimize protection, service restoration and costs. Modeling security threats and defining protective measures. Design and implementation of advanced data processing algorithms for detection, identification and localization of cyber-physical threats based on data from synchrophasor measurement (SPM) units deployed in the energy grid. Pilot demonstration and validation of SPM based threat detection in a real operating environment.

Dynamic Thermal Rating Uncertainty modules
High-voltage transmission lines represent an important segment of the electric power transmission network. They not only connect the production and consumption network in Slovenia, but also connect the Slovenian transmission system with neighboring ones. In the last years, we witness an extremely rapid development of the electricity market and services, mainly due to the inclusion of renewable electricity resources in the network. System operators in recent years have faced challenges in how to ensure maximum transmission capacity of the system to satisfy market needs, while maintaining operational safety and permissible impact on the environment. A great help in the decision-making process was introduced with the Dynamic Thermal Rating (DTR) – an instrument to monitor the temperatures of conductors by using weather and load forecasting to estimate their future trend in order to calculate the ampacity of a transmission line.
The NRG-5 project envisages contributing to the 5G PPP/5G Initiative research and development activities and participation at the relevant 5G Working Groups by delivering a novel 5G-PPP compliant, decentralized, secure and resilient framework, with highly availability able to homogeneously model and virtualize multi-homed, static or moving, hardware constrained (smart energy) devices, edge computing resources and elastic virtualized services over electricity and gas infrastructure assets combined with the telecommunications infrastructure covering the full spectrum of the communication and computational needs. Ultimate goal: The ultimate project goal is to render the deployment, operation and management of existing and new communications and energy infrastructures(in the context of the Smart Energy-as-a-Service)easier, safer, more secure and resilient from an operational and financial point of view.
Our role: Participate in investigating the suitability of the 5G communication network to serve the energy vertical sector, in particular to provide optimal communications of the energy grid services in terms of supporting massive smart metering and very low latency for control and fault localization. Contribute to elastic virtual network functions (VNF) chaining and optimal depoyment and in service level agreement (SLA) monitoring. Participating in two use cases concerned with auto-configuration of smart metering devices to support multi-tenancy in mobility scenarios and with resilience and availability via dispatchable demand response, both requiring high reliability and very low latency.

The essential limiting factor of the power transmission line transfer capabilities is the maximal allowed temperature of the conductor that should not be exceeded to avoid excessive sags. A commonly used conservative approach is to limit transfer capability to the worst case scenarios, i.e. hot, sunny, windless days. Of course, system operators strive to raise the limit with more sophisticated models that take into account actual weather conditions or even weather forecasts. As a consequence, there has been substantial research done on Dynamic Thermal Rating (DTR) models in the last few decades. Based on accumulated knowledge the leading standards in the field published guidelines for thermal rating for operative use. However, the proposed models rely only on empirical relations for determination of the temperature gradient on the surface of the conductor that dictates the heat flux due to the advection. This heat flux is the most intense cooling mechanism in play, and also the most complex to model. In this project, we extend the discussion about advective cooling with a direct simulation of temperature and velocity fields near the conductor with the focus on the natural convection regime. The introduced model considers Joule heat generation and heat transport within the power line and its vicinity, fluid flow driven by buoyancy force, solar heating, and radiation. The solution procedure uses RBF-FD numerical method combined with Poisson disk sampling nodal positioning algorithm, both implemented in our in-house library Medusa.

Sustainable and robust networking for smart electricity distribution – Sunseed proposes an evolutionary approach to exploitation of common, converged communication infrastructures for future smart energy grid services. Its life cycle matches the joint communication networking operations of DSO and telecommunication operator and consists of six steps: overlap, interconnect, interoperate, manage, plan and open. Joint communication networking operations steps start with analysis of regional overlap of DSO and telecommunications operator infrastructures. Overlap is discovering what vital DSO energy grid infrastructure locations (e.g. DEG, substations) are geographically covered by both DSO and telecom communication networks and underlying infrastructure (e.g. ducts, energy cabling). Coverage can be in wireline (PLC, xDSL, fiber) or wireless (WiFi, Gprs, UMTS, HSPA, LTE) technologies. Interconnection step assures communication on the physical layer between DSO and telco, whereas interoperation provides network visibility and reach of smart grid nodes and vital locations from both DSO and telecom sides. A virtual network(s) layer on top of physical infrastructure is formed that ensures secure communication. Monitoring, control and management acts upon measurement data streams from wide are sensors and smart meters. It employs novel intelligent real time analytical knowledge discovery methods. For full utilisation of future network planning, we will integrate various public databases. Applications build on open standards (W3C) with exposed application programming interfaces (API) to 3rd parties enable creation of new businesses related to energy and communication sectors (e.g. virtual power plant operators, energy services providers for optimizing home energy use) or enable public wireless access points (e.g. WiFi nodes at DEG points). SUNSEED life cycle steps promise much lower investments and total cost of ownership for future smart energy grids that will cover large, dense distributed energy generation and e-car charging infrastructures.
Our role: Development and production of prototypes of sensor devices for synchronous measurement of amplitude and phase (SPM) in the distribution electrical systems and for power measurement and power quality management (PMC). Development and deployment of service prototypes for smart grids such as three phase distribution system state estimation, short-term forecasting of events and demand response management. Deployment of SPM and PMC devices into the pilot management system (WAMS). Technical and scientific coordination of the project (Aleš Švigelj).
In February 2014 a severe icing storm hit Slovenia, and caused damage in order of 8.5 million € only on the power transmission network. In cooperation with Milan Vidmar Electric Power Research Institute (EIMV) and Slovenian Environment Agency (SEA) we developed and validated a DTRi model (Dynamic Thermal Rating – icing), which was implemented as a prototype system for operative forecasting and prevention of icing on high voltage transmission lines. We have validated the prototype system with measurements on an experimental site and through reconstruction of two real cases, on 1.2.2014 and 5.1.2016 on Beričevo-Divača line. The results of the study are promising, and therefore the customer decided to promote the system into the operative SUMO environment. For this purpose we also obtained additional founding from EU FP7 TETRACOM project. Both projects are led by members of our program group, while the customer is the company ELES.

Aerial Base Stations with Opportunistic Links for Unexpected & Temporary Events – ABSOLUTE. Recent events have shown that in the aftermath of an emergency, disaster or any related tremendous unexpected events, a reliable communication infrastructure plays an important role in providing critical services including emergency recovery operations, critical infrastructure restoration, post-disaster surveillance etc. In most of the cases, immediately after a large scale disaster, the normal terrestrial network infrastructure is seriously compromised and cannot guarantee reliable and large scale coverage for rescue teams and citizens. Current mission critical communication systems including PPDR (Public Protection for Disaster Relief) systems are heavily limited in terms of network capacity and coverage. They are not designed for or suitable to address large scale emergency communication deployments immediately after the disaster scenarios where these networks can provide dependable and resilient network connectivity at higher data rates over large coverage areas. Moreover, PPDR systems are limited by interoperability barriers and the technological gap with commercial technologies and evolving standards. Furthermore, the first responder devices and terminals are getting smarter with new applications supporting packet data with integrated sensors and other monitoring and the availability of multimode heterogeneous embedded receivers. Such improvements call for a marked increase in capacity and energy demands for the first responder (FR) user terminals. Further, there is a large demand in the PPDR community for higher bandwidth emergency communication infrastructure to cater for the new mission critical services with very high throughput and low-delay requirements during the immediate post-emergency period (including real-time video streaming and video surveillance, exchange of high resolution pictures etc). Also some foreseen/unforeseen events with large aggregation of professional and consumer users such as e.g. big sport events, road shows or concerts require high capacity and/or dedicated coverage that the legacy terrestrial network infrastructure cannot provide rapidly. These factors underline an urgent requirement for a rapidly deployable multi-purpose, multi service and multi-band interoperable and integrated network infrastructure capable of supporting reliable high data rate applications to serve large scale disaster emergency situations and the temporary event scenarios.
Our role: Involved in the definition of the system architecture for large scale emergency communications and temporary events involving satellites and aerial platforms, in network planning and optimization, and in the design and prototyping of sensor network gateway, personal sensing devices and energy management module for the portable terrestrial eNodeB.

Sensor and information management support (SMER+)
Sensor and information management support is a nationally funded applied research project on intelligent caravans.
The “Advanced procedures for interactive composition of sensor networks project” starts from the hypothesis that by applying SOA principles it is possible to develop advanced procedures for the interactive composition of sensor networks on demand and thus exploit shared heterogeneous sensor resources assuming the knowledge of their characteristics, functionality, the context and accessibility. Since we will rely on the use of semantic technologies for discovery and composition of sensor resources we refer to the composed networks as semantic sensor networks. The main objective of the project is to use semantic technologies to annotate and subsequently search for, discover, and reason upon sensor and associated communication resources, and on demand compose those resources into dynamic global sensor infrastructure. By having data on shared sensors instead on available sensor data, we make possible the interaction with sensors, so we can reuse them and set their parameters according to the needs of a particular application.

The PlanetData project is built around three objectives that together ensure the creation of a durable community made up of academic and industrial partners. This community will be supported in conducting research in the large-scale data management area through the provision of data sets and access to tailored data management technology. From the research point of view, the focus is on large-scale data management. Sensorlab provides sensor data, raw and annotated and services based on these.
In the frame of the OPCOMM Competence Centre we will design an open communication platform for the development of new cutting-edge services and applications for the Future Internet. Special attention is given to the applicability of services, quality of user experience, the applicable value of data and content, and the interaction with the “material world”, i.e. various devices, objects and processes. This requires efficient interaction between the smart user terminals, appliances and objects, contextually dependent services, and the communication network. The programme encompasses research, design, and prototype development with the final demonstration of new solutions.
The SensorLab team is focused on gathering different types of data from sensor networks and on context awareness in support of services and application for object management. Moreover, it is concerned with pre-processing of data and metadata and its transfer to the core platform through appropriate data interfaces. In this respect, SensorLab will give special emphasis on the investigation of semantic technologies for sharing, searching, virtualizing and dynamic composition of sensor nodes.
”Cognitive Radio and Networking for Cooperative Coexistence of Heterogeneous Wireless Networks”. The main objective of the Action is to integrate the cognitive concept across all layers of communication systems, resulting in the definition of a European platform for cognitive radio and networks. The Action proposes coordinated research in the field of cognitive radio and networks. The cognitive concept applies to coexistence between heterogeneous wireless networks, that share the electromagnetic spectrum for maximum efficiency in resource management. Several efforts are currently in place in European research centers and consortia to introduce cognitive mechanisms at different layers of the communications protocol stack. This Action goes beyond the above trend by integrating the cognitive concept across all layers of system architecture, in view of joint optimization of link adaptation based on spectrum sensing, resource allocation, and selection between multiple networks, including underlay technologies. The cross-layer approach will provide a new perspective in the design of cognitive systems, based on a global optimization process that integrates existing cognitive radio projects, thanks to the merge of a wide-range of expertise, from hardware to applications, provided by over 30 academic and industrial partners. The final result will be the definition of a European platform for cognitive radio and networks. To reach this goal, algorithms and protocols for all layers of the communications stack will be designed, and a set of standard interfaces as well as a common reference language for interaction between cognitive network nodes will be defined.
- COST Action IC0906 “Wireless Networking for Moving Objects”
The main objective of WiNeMo is to advance the state-of-the-art concerning networking aspects of scenarios integrating moving objects of the most varied kinds, ranging from personal use devices to sensors, into the Internet of the Future. In particular, the Action will coordinate the development of new algorithms, techniques, protocols models and tools that will facilitate the integration of moving objects into pervasive and ambient communications. The Action will foster cooperation among researchers at European and global level by contributing to the coordination and defragmentation of research efforts across Europe in the area by creating an open forum for academia and industry. As a consequence, the Action will play a supporting role to European industry – including SMEs – and will enhance cooperation between industry and academia in the area of networking support for moving objects. The Action will seek active cooperation with existing COST Actions and foster relationships with external bodies such as Internet Engineering Task Force (IETF); Open Mobile Alliance (OMA); the Standardization and Radiocommunication Sectors of the International Telecommunication Union (ITU); European Telecommunications Standards Institute (ETSI), Institute of Electrical and Electronics Engineers (IEEE) and The 3rd Generation Partnership Project (3GPP). The establishment of links with international (e.g. FP7 programmes) and national research projects is deemed as an essential goal which will be proactively pursued throughout the Action’s lifetime.
- COST Action IC1101 “Optical Wireless Communications − An Emerging Technology”
Wireless transmission via optical carriers opens doors of opportunity in areas as yet largely unexplored. Offering significant technical and operational advantages, optical wireless communication (OWC) can be, in some applications, a powerful alternative to and, in others, complementary to existing radio frequency (RF) wireless systems. Variations of OWC can be employed in a diverse range of communication applications ranging from very short-range (on the order of millimetres) optical interconnects within integrated circuits through outdoor inter-building links (on the order of kilometres) to satellite links (larger than 10,000 kilometres). In many respects, OWC research is still in its infancy and calls for extensive research to begin to harness the enormous potential of the optical spectrum. This COST Action will serve as a high-profile consolidated European scientific platform for interdisciplinary OWC research activities, spanning from characterization of diverse propagation media to modeling, design and development of devices, components, algorithms/protocols and systems. It will make significant contributions to the fundamental scientific understanding, technical knowledge, engineering design and applications while promoting community awareness of this emerging field. Development of novel and efficient communication technologies resulting from integrated research activities made possible through this Action will be a significant enabler for future-generation heterogeneous communication networks supporting a wide range of wireless services/applications.
- COST Action IC1104 “Random Network Coding and Designs over GF(q)”
Random network coding emerged through an award-winning paper by R. Koetter and F. Kschischang in 2008 and has since then opened a major research area in communication technology with widespread applications for communication networks like the internet, wireless communication systems, and cloud computing. It allows transmitting information through a network by disregarding any of its topological features. As in traditional algebraic coding theory, two main research directions in random network coding are (1) existence and construction of good and optimal network codes, (2) efficient encoding and decoding schemes for a given network code.
Restriction to the so-called Grassmannian codes has proven to be advantageous and leads to the theory of designs over GF(q). Worldwide, there exists a larger number of workgroups focusing on this topic, which includes several groups located in Europe. This COST Action will set up a European research network and establish network coding as a European core area in communication technology. Its aim is to bring together experts from pure and applied mathematics, computer science, and electrical engineering, who are working in the areas of discrete mathematics, coding theory, information theory, and related fields.
- ESA PECS project “Satellite Propagation Slovenia – SatProSi”
SatProSi, project “Ka/Q-band Propagation Measurements and Modelling for the Design of Prediction and Impairment Mitigation Techniques” is a 3 year project for the European Space Agency (ESA), performed in the scope of Plan for European Cooperating States (PECS). The main goal of the project is to establish a Ka-band band satellite-beacon measuring site in Ljubljana, Slovenia and to statistically analyse the results. The task has already been successfully accomplished. SatProSi has thus become the first such satellite propagation experiment, to be carried out in Slovenia as well as in the broader region of the Balkans.
A low-cost beacon receiver has been developed specifically for the project, based on SDR (Software Defined Radio) technology. A GNU Radio software development toolkit and USRP (Universal Software Radio Peripheral) were used for application development. The application has been made publicly available as an open source code via the GitHub hosting service (https://github.com/urbank/beacon).
In 2013 a network of three low-cost SDR-based Ka-band beacon receivers has been established for the purpose of site diversity experiment, one in Ljubljana and other two at the distance of 26 and 40 km from Ljubljana (Lisec, Krvavec). More than one year of measurements, collected in Ljubljana, has already been processed and statistics of in-excess attenuation and rainfall rate have been calculated.
In the future, the project team aims to take the project to the next level, by conducting measurements of the Q-band beacons from the Alphasat satellite.
